the guy here on the forum said that 274wTQ was too high , he probably meant that the dyno read high because 274wtq is more than what we usually see from a fully modded VHR engine.

I did mentioned that you were pretty much spot on with your mod at 299whp. but I can see the 274 being a little bit high than average. its also depend on your setup. so don't feel bad.

as an example here on my dyno sheet , the only way I could be at over 275wtq was using a lower gear on a dynapack.
I proved this dynapack to be within 1% read(higher) from a dynojet a couple hours prior during that day.

in average the guys get like 265wtq *peak*
it will be different when someone is using a different intake manifold like the M370 since it shift the TQ down by like 300-400rpm which gives a small Tq gain in mid-range. due to longer intake runners.

Edit;
Also keep in mind about the SAE Vs STD dyno reading . STD being higher.

this dynosheet is in SAE.

Well, I'm not an official Pro Tuner, but I tuned a few different cars and I never tried this. Nissan made an update and it finish with an higher letter.
as example on my VHR ECU they made 1 update.
1EA4B / 1EA4A
they have several different Rom per year and some has update.
As long as you stay within what your ECU accept . there will be no problem.

All I know is I think you cant flash a rom with a complete different serial.
depending on the serial you have. I remember at one point where my VHR was the primary and I wanted to flash my HR Ecu . it just didn't work. Wrong system file, something like this.

Rom
 

Let me start by saying thank you,....... Just so I understand a tuner Can Not Flash a random ROM from some other 370z on to some one else's ECU because of serial numbers??

correct!!!!

This is why I ask if a ROM from a different car can be used on another car :

"I can't post the ROM file because of size limits. Shoot me your email if you want my current ROM file"

This is a question someone asked !!??

I don't know why you just email Uprev they will give you a back to stock file and a Uprev stock file and your good to go it is free and takes about 3days.

agree with this !

I asked the C version of my HR Ecu on Sunday night and I received the reply back with the file around noon today.;)

Keep getting a Raddling / Rasping sound, I'm being told that its from the Berk test pipes do you know anyone else with the same problem real don't like it. Would changing them out for long tube headers solve my problem???

Rasp is really common with test pipes. Headers would likely make it worse.
